IMPROVEMENT IN REFRlGERATOR-BARRELS.

Specification forming part of Letters Patent No. 178,094, dated May 30,1876; application filed May 2, 1876.

To all whom it may concern:

Beit known that I, ROBERT C. ARMSTRONG, of Alexandria, in the county ofAlexandria and State of Virginia, have invented a new and usefulImprovement in Refrigerator-Barproper refrigerating materials, inclosedby an outer barrel sufiicientlyplarge to afi'ordintermediate spaceforholding non-conducting material, the inner barrel being provided with anoutlet-tube communicating with the open air, as will be fully describedhereinafter.

In the drawings, Figure 1 represents a perspective view of the barrel incondition for shipping; Fig. 2, a central vertical sectional elevation,and Figs. 3 and 4 partial views of the barrel-heads and outlet-tubeenlarged.

To enable others skilled inthe art to make and use my invention, 1 willnow proceed to describe fully its construction and manner of operation.

A represents the inner barrel, which may be constructed, of course, ofany proper size and suitable material. B represents the outer barrel,which exceeds the inner in size sufficiently to afford proper space forholding non-conductin g material, as shown, sawdust being preferred.O'represents an outlet-tube, opening at one end into the interiorspaoeof the inner barrel, and at the other into the open air, as shown,it being held in place by suitable perforations in the heads of thebarrels, and also by the flange c, which is nailed or otherwise properlysecured to one of the heads, as shown. i

put into place, the remaining space may be filled with the sawdust, andthe other parts of the'head inserted and secured.

Some of the advantages arising from the.

use of this invention are as follows: A cheap package is furnished, bymeans of which fish can be transported long distances in warm weatherwithout danger of spoiling. The outlet-tube, being always open, permitsany gases that may form to escape, andi'urnishes also a means fordischarging the water resulting from the melting of the ice. The sawdustin the intermediate space absorbs the water escaping from the innerbarrel, and prevents other packages in transit with it from beinginjured by its outflow.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is a A transportationrpackage forfish, consisting of an inner andouter barrel, intermediate packing, anda single outlet-tube, the whole' constructed as described.

This specification signed and witnessed this 29th day of April, 1876.
